MEASURING INSTRUIviENT.

To all whom it may CONN/)1.

Be it known that I, r i'rni-xxasn s GIAN- NOUSIS, a subject of the King" of Greet-e and New York, have invented certain new and useful Improvements in Measuring instruments, of which the following is a full, clear, and exact description.

This invention relates more particularly to a trigomnnetrical instrument to be used in piloting and for other purposes.

The primary object of the invention is to provide a simple and ctlicient device which. may be used in connection with navigating to determine the course, the dili'erence of latitude, and distance with relation to a vessel when certain features are known, and to provide an instrument which may be also employed when. piloting a vessel, and which rts thereof may be readily and quickly adjusted so that the result sought may be accurately and quickly ascertained, thus ovt-trcoming many of the objections incident to the ordinary methods employed [or such purposes.

Another object of the invention is.to provide a simple and ellicient instrument which may be used to determine from the land the position of an object on the water, as a vessel, when the distance between two points on land is known.

A further object of the invention is to pro 'vide a simple instrument which may be employed for solving various tl'lg'OlIUlHCbl'iGtll problems instead of using the tahleof logalithms.

With these and other objects in view, the invention. will be hereinafter more particularly described with reference to the accompanying drawings, which form a part. of this specification, and will. then be pointed out in the claims at the end of the description.

1n the drawings, Figure l is a sidc clcva tioh of one form of instrument embodying; my invention showing; the parts thereof in use and in. one of their open positions. l I L is a detail elevatiim oi' the part when mu in use. .l i 4. 3 is a sectional view talwn on the line lll-ll.l. oi Fig. 2. Fig. -l is a sectional view taken on a: line l ol- Fig. 22 l igs. 5 and 6 show a dill'erent means that may be employed for adjust lug on of t he parts; and Figs. 7 and b arc diagrammatic views showing; how the position of an obit-ct may in. determ ned by mean ol' the instrument.

have its parts varivariously arranged other to adapt it for the various purposes for which it may be used and may be made ol any suitable material. As shown it comprises a normally lixed bar, lot;- or member 10 and two movable bars, legs or members 1 and 12, and on theiixed memb r it) are located two protractors l3 and 14, the l'ormer being normally lived to the member lo, and the latter being; movable along said member 10.

For the purpose of understanding one form of the invention 1 have indicated a scale on ca ch of the members, and each of the charactors may indicate a fraction of a mile or a multiple of miles according to the purpose for which it is used, or other n'ieasurements or characters may be placed thereon, and when said instrument is used for navigating purposes, the member It) may be employed to indicate the dili'ercncc of latitude, the member H the distance, and the member 12 the departure. Each of the protractors if and 14 is provided on the inner side, as at 15, with compass characters, and on the outer side, as at 16, with a scale indicating the various degrees, and these degrees may be one hundred to each right angle or may have the usual division oi ninety degrees as shown.

The member 12 is always placed at right angles to the member It), and at ninety degrees for navigating purposes, and for piloting may be used at any degree, and said member I: may be pivoted centrally oi.the protroctor 13%. at 17, so as to permit said. member to be moved about the protractor lb, and also to be folded in close relation to the member In when not in use. l'hc menu bcr It is pivoted at 18 to a slide It) to which is held the protrm-tor member 14, and carried b lhc slide It? is u pointcrZtl whi h is adapted to indicate the tilSbtlnfO the center ol the The instrument may )rot ructo! is from a 'iven mint on the memt h To move the protra tor and member 11, any suitable means maybe emplo ed. As shown the ends ol' the member 10 are providcd with lHZH'lUiS 2t and 22, and rotatablv held in said brackets is a threaded rod 23 which engages a threaded aperture in the slide 15), and on thccud of said threaded rod LL; is a head or lingering part ?-l b which the said slide It), mcmbci' ll, and protractor l t may be adjusted to dili'crcut distances from the center of the pl'oti'aclor i5,
